Thanks Jim.

Your compile seems to be 2 x as fast in Knps.

I must be doing some thing wrong in the Makefile:

Code: Select all

Hi David,

Your compile seems to be 2 x as fast in Knps.
I must be doing some thing wrong in the Makefile:

Latest Intel compiler produces the fastest code of any C/C++ compilers at the moment.
Gcc compiles can get a boost from these extra switches >

Code: Select all

-fexpensive-optimizations -ffast-math

Most performance will be squeezed out if you perform a profile optimised build.

add

Code: Select all

-fprofile-generate

run some testuites/games, then finally compile with

Code: Select all

-fprofile-use

plus the other switches.

best,
Jim.

New Logo for Xpdnt!

Hi Swami,

New Logo for Xpdnt!

A nice effort. It may be coincidence, but I can see a certain,
dare I say 'Banks' influence in the design, which isn't a bad
thing at all

best,
Jim.

Thanks for a compliment,Jim. Actually I asked Graham a few days ago on how to make a logo, he said he uses paint, gets the free pictures available on the net, and resizes them to make changes...

Thanks Swami

Thanks Jim,

I'll add those lines some time.

At the rate I am going with Xpdnt's improvement, it will be playing Losers Chess soon!

No, It actually plays pretty well in my tournaments, good blitzer.It finished first in a division IIRC.
